Hunter in Immortal Academy

This is my first novel, so please be open to any and all reviews. Xian Yu who died due to last stage cancer transmigrated to another world in different dimensions where dungeons and hunters exist. Hunters were naturally gifted by gods having more strength and combat power than normal people. Xuan Yu, even after transmigration, did not have a system or any other cheat. He was a regular person who suddenly found immortal academy online. The one meant not for hunters but cultivators. Let's walk with xian you as he conquers SSS grade dungeons and transcends immortality with it.
